I like the idea of a heated airer but surely it can't be good to release litres of water into a bedroom every day - doesn't it cause damp?

No different to using a normal airer or radiators. We keep ours in the dining room and have chimneys in each room as it's an old house, never had a problem yet. Probably good to have a window open if using upstairs though.

No it's not good to release that much moisture into the air... & yes it does cause damp, unless you've got a draughty house.

We've got double glazing, cavity wall insulation & masses of loft insulation, so we're a pretty airtight house, meaning that moisture build up just from every day living is bad enough. The north facing wall, particularly in the winter, is really prone to collecting the damp & building up mildew, so we usually have a dehumidifier running for a couple of hours upstairs & downstairs to help combat it, when it's too cold to open the windows. And that's without drying any clothes indoors, apart from in the tumble dryer.
